Xemnas was difficult cause his color is very similar to Xion's. I had a hard time trying to make his color distinguishable from Xion's without straying away from the consistency of the set. In the end, the only way I could think of was to make the wallpaper a bit darker than the rest, killing the whole consistency idea =__= But I figured that he should get some sort of special treatment for being the leader the group XD
